'lFhe additional material above referred to may be laze, sli in a fluid or semi-fluid state such as engo e, clay in a more or less plastic state and of the same or a difierent color relatively to the ware, powdered, granular-or fluid coloring or decorating material, and analogous decorative and utility mediums.

The apparatus in general is shown as be ing disposed to operate on the ware subsequent to the iiggering operation and prior to being passed through a drier, the molds on which the were is formed being carried on recessed trays such as those disclosed in my co ending application Serial. No. 269,273, filed pril 11, 1928, the trays being mounted in series in a conveyor, the construction and operation of which may be rendered more clear by referring to my copending application Serial No. 202,629, filed June 30, 1927.. However, the Wars may be treated at any sta e of the fabricating operation and the mo ds may be dis osedin position either man- .uall or automaticall the present invention the molds, indicated at A, being carried on trays 7, the latter being provided with projecting trunnions 7" having grooved rollers 7 preferably comprises a 7' thereon by which said trays are mounted in series in a flexible conveyor 8, the rollers having movement on and being'guided by said tracks while the conveyor moves adjacent thereto, as shown in'plan view in Fig. 3. Supplemental frame units?! are adjustably secured or clamped on cross bars 10, which in turn may be secured to, or form part of the frame 5, said frame units serving to support the chuck assembly which in the present instance comprises telescoping spindles 11 and 12 in spline-sliding engagement, the spindles 11 having bearing at their lower extremities in the frame units or castings 9 and the spindles 12 terminating in chucks 13. The lower portions of the spindles 12 are grooved or necked to receive the one extremity of cross forks 14, the opposite extremities of said forks being adjustably connected as by nuts 15 to pitmen 16, which have vertical slidable bearing in the frame units or castings 9. Levers 17 are pivotally connectedat one extremity to the pitmen 16 and at their opposite extremities said levers are adjustably and pivotally supported from the frame units 9, the pivotal connection being illustrated'in detail in Figs. 5 and 6.

Referring to Figs. 5 and 6, the assembly pivot or journal block 18, which is journaled in a longitudinally slotted portion of the lever or member to be pivoted or fulcrumed, indicated at L, and bored and threaded for insertion of an adjusting and retaining screw 19, said block being also mounted to shift or slide through adjustment of screw 19 in a longitudinally slotted portion of a block or analogous member 20, the journal or bearing portion of block 18 being headed and the side walls of the longitudinally slotted portion of lever L formed with a retaining track or groove 21 for said head. Block'20 is adjustably secured to the supporting bracket or casting 22 of the assembly as by screw bolts 23 and 24 and positioning pin 25, the casting or bracket 22 being arcuately slotted as at 26 where the bolt 23 extends therethrough and a plurality of positioning holes '27 provided in the bracket 22 for pin 25. By loosening bolts 23 and 24, pin 25 may be adjusted in any of said holes to definitely locate or spot i the angular position of block 20 relatively to the bracket or casting 22 and lever L, while screw bolt 23 may be adjusted in slot 26 to accomplish the same result independent of pin 25 and intermediate of holes 29. Adjusting screw 19 is journaled in end plates 20*, which are secured to block 20, said screw being provided with a thrust'or bearing collar or set nut 28 and adjusting crank or handle 29. It will be seen that by turning screw 19, journal block 18 may be shifted in the guideway provided therefor and thus shift the pivotal or fulcrum point of lever L and vary the throw of said lever or theextent of recip'rocation thereof from a stationary point and while in operation and while the driving and pivotal connection subsists. By adjusting the angle of block 20 and /or shifting the block 18, various advantageous adjustments may be obtained. For instance, the extent of reciprocation of lever L may be varied without varying the lowermost point of reciprocation, or the ciprocation may be maintained constant while at the same time varying the extent of reciprocation, or the lowermost point of reciprocation may be varied to a greater or less extent than the uppermost point of reciprocation, and vice versa, or the altitude of reciprocation varied.

The foregoing assembly as a whole may in turn be adj ustably supported by a turn-buckle intermediate point of reor analogous member 30, threaded at opposite extremities in brackets 31 and 32, said turnbuckle being also adjustable to raise and lower the pivotal or fulcrum point of lever L, and to provide for both vertical and lateral adjustment independent of the turn-buckle, or as an alternate method of supporting the assembly where the space available may not be sufficient to accommodate the turn-buckle assembly, the bracket or casting 22 and bracket 31 or other supporting member are slotted as at 33 and 34, to receive securing bolts 35. By loosening bolts 35, the assembly as a whole may be adjusted both vertically and laterally.

Figs. 7, 8, 9 and 10 show a cam-mounting structure wh'ch may be adopted with a view to permitting change in the phase of motion of the parts primarily actuated by the cams to which said structure may be applied while said parts are in operation and while the driving connection subsists. To illustrate,

a cam is shown applied to a shaft 8, which is formed with an annular threaded groove 37 of the cam in Figs. 7 and 8, the hub being formed with a bracket portion 37 a which may be bored to form a bearing housing for an adjusting and set screw 38, the latter being formed with, or having secured thereon a gear or gear head 39, the one extremity of the screw, housing or here being enlarged to receive said gear and internally threaded to receive an externally threaded retaining plu or nut 40. The hub and cam may be provide with a guide bore or slot extending at ri ht angles to the screw 38, said bore or slot eing adapted to receive a rack 41, in mesh withgear 39, said rack being suitably secured at one extremity to a collar 42 pro-.

in the groove d3 of collar 42. The threads of annular groove 36 and screw 38 are preferably of the irreversible or single-thread type, to prevent angular displacement of the cam due to work imposed thereon. It will be readily understood that by adjusting screw 44, the rack 41 in mesh with gear 39 will cause screw 38 to turn and thereby change or adjust the angular position of the cam relatively to shaft 8, and this adjustment may he made while the driving connection subsists and while the shaft is in motion from a stationary point, the extent and position of adjustment being visible.

Figs. 9 and 10 show a modification in structure relatively to Figs. 7 and 8, to adapt the phase-changing adjustment structure to a smaller space and smaller or different types of cams. In this instance the screw 38 is inserted directly in the cam, the latter being formed with a bore for this purpose, said bore terminating in an enlarged slot or recess 46. The teeth of gear 39 in this instance may be of such depth or extent as will permit said teeth to project radially beyond the side walls of the cam. in assembling, the screw 38 may be inserted in the bore and the gear 39 in the slot 46 and the said bolt threaded into said gear and secured as by a countersunk screw 47. An adjusting segment 48, see Fig. 12, formed on one extremity of a rocking lever 49, latter having a balancing or weighted head 50, may be used as a contact member for adjusting purposes, said lever being shown mounted ona bracket shaft 51 formed with a longitudinal groove 52, a screw 53 being threaded through the lever 49 and projecting into said groove, said lever being thus limited in its rocking movement by screw 50 contacting with the side walls of groove 52. The weighted head 50 of lever 49 serves to normally maintain the segment out of range of the projecting teeth of gear 39 or out of the radial path of said gear. To adjust the cam, the lever may simply be rocked iiiwardlv to bring the segment 48 within the radius of the projecting teeth of gear 39 as the cam rotates, this adjustment being reversed by sliding the said lever along its supporting shaft 51 and engaging the teeth of gear 39 on the opposite readily gauge the extent of adjustment, as at each rotation of the shaft and cam, the segment contacts with and imparts a definite degree of rotation to screw 38, so that the op-.

, with cams 54, preferably adj ustably mounted asin Figs. 7 and 8 on a shaft 55, which may be of suiiicient transverse extent as to accommodate the number of units employed and side of the cam. 'lthus the operator may have hearing at opposite sides of the stationary frame of the apparatus.

The casting of the frame units 9 is suitably bored to provide housings for the lower extremities of the spindles 11, the latter being formed with annular bearing groovesand the housings may also be formed with annular grooves in registration therewith to receive bearings or, as shown in the present instance, bored to receive bearing pins 56 which also serve to prevent longitudinal displacement of the spindles 11. The frame units 9. are formed with bracket portions 57, levers 58, formed at one extremity with gear sectors 58, being pivotally secured, preferably as in Figs. 5 and 6, to said bracket portions as at 59, arcuate slots 60 being formed in the lower enlarged portions of levers 58 and the bracket portions 57 being provided with studs or pins adapted to be received in said slots, to prevent longitudinal displacement of said levers.

The gear sectors 58 are adapted to mesh with pinion gears 61, adjustably secured on the lower extremities of the spindles 11, and the levers 58 are provided with cam rollers 62, adapted to contact with cams 63, preferably adjustably mounted as in Figs. 7 and 8 on a shaft 64, which may also'be of such transverse extent as to accommodate the number of units employed and have bearing at opposite sides of the frame of the apparatus. lit will be seen that the. cams 63 serve to actuate levers 58 and impart intermittent rotation to the chucks 13, and these cams as well as the chuck-reciprocating cams 54 may be contoured to suit the work to be performed, as will hereinafter appear. The levers 58 are retracted by springs 58?, which are secured at opposite extremities, respectively, to the frame units 9 and levers-58.

Referring now to the upper portion of Fig. 1., the various units are supported from a platform or top plate 5, which is adjustably secured to and supported by side frame members or rails 5", the latter in turn being supported by columns or uprights 5, see Fig. 3. forming part of the main stationary frame of the apparatus. Guide posts 65 are adjustably secured as by nuts 65 to the platform or top plate 5, the upper extremities of said posts being threaded and" extending through enlarged openings in said plate, these posts 65 being adapted to guide and support supplemental frame units generally indicated by the reference numeral 66., the lower ends of said posts being formed with stop heads 67, which in some instances support the frame units 66 when in their lowermost position and act as a stop for said units. The lower portion of each frame unit 66 is formed with a transverse dove-tail groove, indicated bydotted lines at 69, a bar 69 being mounted to slide horizontally in said groove, said bar being formed with a bracket portion at one extremity to receive an adjusting screw 70. A leno- I ver 71 is pivoted at its lower extremity to frame unit 66 as at 72. The upper transverse portion of the frame unit 66 is formed with a further dove-tail groove, also indicated in dotted lines, for slidably supporting a bar 73 in a horizontal plane, said bar terminating at the left as viewed in Fig. l a suitable distance from the end of the said groove, thus providing a seat for a compression spring 74, adjustable through the medium of a screw 75, the bar 73 being adjustably maintained under longitudinal pressure by saidscrew and spring. A suitable cam-contacting member or bracket 76 is secured to the bar 73, and to connect the bracket 76 and lever 71 in readily 77 is pivotally secured to said bracket and lever, aplurality of securing holes being provided in lever 71 and bracket 76, so that the turn-buckle may be adjustably mounted thereon and adjusted at varying elevations to adjust the throw of lever 71. A cam 78, see Fig. 1 is adjustably mounted, preferably as in Figs. 9 and 10, on a shaft 7 9, said cam being adapted to contact with bracket 76 to impart horizontal movement to the bar 69 and such devices as may be secured thereto or supported thereby.

Each supplemental frame unit 66 is formed with a further dove-tail groove, to receive a bar 80, shown in edge elevation'in Fig. 2, a further cam-contactlng bracket 81 being secured on said bar and the latter being adapted to work against a spring 82, adjustable by screw 83, in a manner substantially similar to the bar 73. The bar 80 has horizontal sliding movement imparted thereto by a cam 84, see Fig. 1", also adjustably secured as in F igs. 9 and 10 on the shaft 79, the latter preferably being of such transverse extent as will accommodate the number of units employed and having bearing at opposite sides of the mainstationary frame of the apparatus.

To impart vertical movement to the frame unit 66, a lever 85 is pivotally and adjustably secured at one extremity to the frame unit 66, the latter being formed with a bracket or ear 86, adapted to receive a pivot bolt 87 mounted on one extremity of said lever and adj ustably secured as by set nuts or analogous means, and at its. opposite extremity said lever 85 is pivotally and adjustably supported as in Figs. and 6 from a bracket 88, which may form part of or be secured to the platform or plateb, the pivotpointof lever 85 being indicated at 89. The lever 85 is provided with a cam rolleradapted to contact with a cam 90, shown in Fig. 1, said cam also being secured on the shaft-7 9 preferably as in Figs. 9 and and whereby its angular position may be adjusted while the apparatus is in operation.

adjustable association, a turn-buckle It will be seen that the cams 7 8, 84 and 90 serve to impart lateral or horizontal move/- mentto the bars 69, 7 3 and 80 and vertical or reciprocatory movement to the frame unit 66, and it is obvious that these cams as well as other cams herein illustrated may be given such contours or shapes as will serve to produce the required movements in accordance with the work involved.

A decorating and shaping head assemblyand actuating mechanism therefor, partly shown enlarged in Fig. 4,-is supported from the bar 69 and also from a bracket 91,

the latter being suitably secured to the platform or plate 5, said assembly as shown in Figs. 1 and 4 comprising a head generally indicated at 92, the latter in turn compri ing a clay-contacting portion or facing 93, preferably of porous material such as plaster or bisque, said facing being removably and replaceably secured to a block 94 as by a ring clamp 95, said block and ring being provided with cooperating lugs or cars 96 adapted to receive securing bolts 97. The facing 93 is preferably chambered as at 98 and provided with removable and replaceable treating and decorating members 99, the latter being adjustably mounted and adapted to serve various functions, such for instance as nozzles to convey a treating and decorating medium to the clay charge or ware and/or dies for forming or applying incrustations, indentations, projections or other configurations in or on the ware. The block 94 is threaded on a tool holder 100 and suitably secured as by a pin or screw 101, said sleeve 100 being adapted to receive and have bearing in a further block 102, a gear 103 being secured on the upper extremity of the sleeve 100 as by a countersunk screw or analogous means.

The upper annular portion of the holder 100 is formed with a flange 104, see Fig. 16, the interior of the sleeve providing an orifice or well 105 terminating at its upper extremity in a hopper 106, and at its lower extremity opening into the mold or ware-receiving portion or cavity of the facing 93. In assembling, the gear may first be applied on the holder 100 and secured and said holder then passed through the block 102 and threaded into block 94 and holder 100 are bored, to provide passageways or ducts 107 and 108 leading into the chambers 98, the block 102 being formed with annular grooves 107 and 108 and also bored as at 107 and 108, the passageways or ducts 107 and 108 and bores 107 and 108 registering with said grooves, thus providing a means for conveying a suitable fluid or other medium to the chambers 98 through the block 102, holder 100 and block 94. The bores 107 and 108 are provided with nipples 109 and 110 for connection of suitable hose or block 94 and secured by pin 101. The a ltd lltl

till

other flexible members leading to a control valve, to be described.

it may also be desired to heat the facing 93, in w ich event suitable coils 111 may be disposed in the chambers 98, these coils being supplied with electric current in any well known manner, as by providing the block 94 with commutators 112 and 113 insulated therefrom and the block102 with a brush-supporting bracket 114, brushes 115 and 116 being mounted on said bracket and adjustable to contact with said commutators. Each coil is grounded to the block and the latter in turn provided with a ground contact member as at 117, a ground wire being connected to said member. It is preferred to control each coil independently so as to provide selective heating means for the facing 93.

The gear 103 may be of varying sizes as best suited for the work involved, and said gear is adapted to mesh with a gear 118, suitably secured on a stub shaft 119, which projects into the block'102 and has bearing therein, said shaft 119 being driven or rotated through the medium of afiexible or universal coupling, generally indicated at 120, from a drive pinion or gear 121, see Figs. 1 and 2, which is suitably secured on a further stub shaft 121 having bearing in an extension of the bracket 91. The coupling 120 includes. a sleeve 120 and stub 120 in spline-sliding engagement therewith, so that the coupling may automatically extend itself during shifting action. A lever 122, formed with a toothed sector 122, is adjustably and pivotally secured as in Figs. and 6 to a further extension of the bracket 91, as at 123, said lever being provided with a cam roller adapted to contact with a cam 124, preferably adjustably secured as in Figs. 9 and on the shaft 79. A spring 125 connects at opposite extremities, respectively, to the lever 122 and bracket 91, to retract said lever when actuated by cam 124. This cam and lever assembly is substantially similar to that shown at the lower portion of Fig. 1 and hereinbefore described, and likewise, the cam 124 may be substituted by difi'erent shapes of cams adapted for the work involved.

lhe shaping head assembly is preferably pivotally supported from the lower horizontally sliding bar 69, the block 102 being formed or cast with a stub shaft 126, see Fig. 2, having a gear 127 suitably secured thereon, the said shaft 126 having bearing in a bracket 128, which is secured to the bar 89 as by screws 128; The shaft 126 is prevented from displacement by a collar 126 secured as by a screw or the like on said shaft. To tilt or rock the head 92 an angle lever 129, see Fig. 1, is adjustably iulcrumed as in Figs. 5 and 6 at 130 on the su plemental frame unit 66, the one extremity 0 said lever being pivotally and adjustably connected to the cam-contacting bracket 81 as by a turnbuckle 131, a pluralit of securing holes beingprovided in said lever and said bracket so as to permit adjustment of the position of said turn-buckle thereon, and the opposite extremity of said lever is provided with a pin or analogous member 132, adapted to engage in a slot 133 formed in a T-head 134, which may be cast or formed on the up er extremity of a rack 135, the latter extendlng down and being adapted to mesh with the gear 127. secured on the stub shaft 126 of block 102, a suitable retainin and guide bracket 136 being provided which may be cast integral with or be secured to the bracket 128 on the slide bar 69.

It will be seen that whencam 84, in contact with bracket 81 on slide bar 80 rotates, it will actuate lever 129 fulcrumed on the vertically slidable frame unit 66, said lever in turn actuating rack 135 in mesh with gear 127, to thereby tilt the head 92, this tilting action being under ready control and adjustable while in operation as to phase, by adjusting cam 84, extent or degree, by adjusting fulcrum point 130, and angular position by adjusting turn-buckle 131, and through the medium of the cam, 90 acting on lever to reciprocate the frame unit 66, the head may be recipr'ocated vertically, the phase and extent and altitude of vertical reciprocation being also under ready control while the apparatus is in operation by adjustin cam and/or pivot point 89 of lever 85, and during this tilting and reciprocating action the head may be rotated through the medium of cam 124 acting on lever 122 to rotate gear 121, the drive being transmitted to head 92 through the medium of flexible coupling 120 and gears 118 and 103, the phase of rotation being under ready control by adjusting cam 124 while in operation and while the driving connection subsists, and by varying the lvotal connections 59 and 123, the speed and extent of rotation of the chuck 13 and/or head 92 may be va-; nod and adjusted while in operation or while performing their respective functions. The

shafts 79 and 64 are referably driven in synchronism, so that uring reciprocation and rotation of the head 92, the chuck 13 with the mold A and were thereon may be given any desired relative rotation and reciprocation in accordance with the work involved. As heretofore specified, any number of different styles and shapes of cams may be provided, those herein shown being simply to illustrate the adaptability of the apparatus to the method.

Means are providedfor automatically supplying the surface of the formed or partly formed ware with a suitable coating of material in synchronism with, and during ogaeration thereon by the head 92, one form 0 said means being herein illustrated as a pug-mill maintained in contact with the gear compression spring148, see Fig. 3.

The rack 144 is guided and prevented from displacement by a guide bracket 148, which may be secured to or cast integral with the cover plate 142 of the container 138, the rack being provided with teeth which intermittently mesh with said gear 143 to rotate the latter in one direction, said rack being by a At an intermediate point the lever 145 is provided with a cam roller 145, adapted to have movement in the groove or track of a cam 149, which is preferably adjustably secured as in Figs. 7 and 8 on a shaft 150, which may have bearing at opposite sides of the main frame of the apparatus and also in the supporting bracket 140. The container 138 is provided with a hopper 151 and an outlet orifice 152, and to regulate the pressure of the material at the orifice extremity of the container, the wall of the latter is formed with a longitudinal chamber 153 having a valve-controlled inlet 154 and terminating at its outlet extremity in thehopper 151. The inlet 154 to the chamber 153 is shaped to seat a valve generally indicated at 155, said valve being normally seated in the inlet 154 and retracted from seated position against the presure of a suitable compressing spring, the latter being adjustable through the medium of an adjustable bushing or sleeve 156, adapted to receive the valve stem and provided with an adjusting and set nut or analogous member 157, see Fig. 3. By adjusting the tension of said spring,

-' the inlet 154 may be controlled so as to permit the material in the container to pass therethrough and into the chamber 153 under a predetermined maximum pressure, the matethe hopper 151' As the material is extruded through the orifice 152 of the pug-mill or container138, itis segregated into charges, and with this end in v1ew a wire, knife or analogous mem-.

her 158, see Fig. 3, is mounted in the yoke extremity of a cutter bar 159, the latter being pivotally secured to the one extremity of a lever 160, the opposite extremity of said lever being adjustably pivoted at 161, the pivoting assembly preferably being in the form shown by Figs. 5 and 6 and supported from a bracket 162-, which is secured to the platform or frame plate 5*. The lever 160 is provided with a cam roller 160, adapted to contact with a cam 163, which is adj ustably mounted as in Figs. 7 and 8 on the shaft 150. The orifice extremity of the container 138 may be formed with, or have secured thereto a guide bracket 164', which is formed with guide grooves 164, see Fig. 3, adapted to receive the bracket extremity of the cutter bar 159 and also an orifice regulating slide or gate valve 165, which is formed on one extremity of a bar 165' and provided with a turn-buckle 165 to adjust its position, the said bar 165 being pivotally secured to the one extremity of a lever 166, formed with a fulcrum slot 167 and fulcrumed at 168 referably as in Figs. 5 and 6, the assembly eing adjustably supported from a bracket 169 which is secured to the platform or frame plate 5?, said bracket being of angle construction and provided with a plurality of threaded holes 170, see Fig. 3, to receive the supporting bar 168* for the fulcruming assembly.

As the material is segregated in suitable charges, it is conveyed to the hopper portion 106 of the chamber, well or orifice 105 of the head 92 through the medium of a chute 171, which is pivotally secured at one extremity as at 172 to an upright or standard 173, which may form part of, or be secured to the block 102, and at its opposite extremity said chute is adjustably and movably supported by a bracket 174, the latter being cast integral with or suitably secured to the container 138 and formed in sections and connected by a coupling or union 175, the lower extremity of the bracket bein provided with a roller 176 adapted to mova 1y support a guide rail 177, the latter being cast integral with or forming part of the chute 171.

The material may be applied by pressure over the surface of the ware by a plunger 178, adapted to work in a cylinder 1 9, said plunger being provided with a piston 180 at an intermediate point and a stem 181, the latter having a sliding fit in the upper end of the cylinder and threaded to receive a contact collar or nut 182, adapted to contact with the one extremity of the valve-regulating lever 166, and the cutter bar 159 is also provided with a contact member or pin 183 adapted to contact with the opposite extremity of lever 166. The cylinder 179 may be bolted or otherwise secured to a bracket 179, which in turn is secured to the block 102, said bracket also serving to stabilize the stub shaft 119. The plunger 17 8 is preferably actuated by a1r under control of a preferred type of valve which will presently be describe and regulated so that if an excess amount of material is delivered into the chamber or well 105, only the required amount will be pressed out over the surface of the ware, ing depressed a certain distance into said chamber due to excess material preventing further descent. Thus, by adjusting the contact nut 182 on stem 181 so that it will contact with and actuate lever 166 to raise valve 165 such distance as will reduce the orifice 152 of container 138 to a predetermined extent, a correspondingly reduced charge will e extruded from the container, and as the cutter bar 159 lowers, contact pin 183, which may be adjusted to a predetermined position, again actuates lever 166 which lowers the valve to its original position, so that by properly adjusting contact members 182 and 183, the charges of material may be automatically equalized. The cylinder 179 is rovided with nipples 184 and 185, adapted or connection of hose or other flexible members leading to the control valve above referred to and hereinafter described.

Where the material is in such fluid or plastic state as may not be suitable for the pugmill assembly just described, the charge applying and measuring device illustrated in Fig. 13 and generally indicated by the reference numeral 186 may be used. This device may be adjustably supported from the platform or frame platen by a bracket 187, the lower extremity of the latter being of angle shape and bored to receive an externally threaded sleeve 188, the latter being adjustably secured as by adjusting and" securing nuts 189, the lower extremity of said sleeve terminating in an externally and internally threaded head adapted to be threaded into the charger casing 190, which is internally threaded at the up er portion thereof, said casing being provi ed with an inlet port 191 and outlet port 192, controlled by check valves or analogous means, the port 191 having a hose or other flexible member 191 connected thereto and leading to ply such as a slip tank or the and the port 192 having a similar member 192 connected thereto and leading to the chamber or well and/or nipples 109 and of the head 92, or to any other point of application of the material. A further port 193, also controlled by a check valve, is formed in the casing 190, said port having a hose or other suitable flexible member 193 connected thereto and leading to a source of deposit of slip that may seep past the plunger 194 of the device. The plunger 194 is provided with a stem 194 having a sliding fit in the sleeve 188, the upper extremity of said stem projecting through the platform or frame plate 5, a suitable compression spring 195 being disposed around said stem and hearing at opposite ends respectively against said plate and a collar 196, which is adjusta source of supthe plunger only belike, not shown,-

ably secured on said stem to adjust the tension of spring 195. The piston 194 and sleeve 188 may be provided with packing and packing gland to prevent leakage.

To reciprocate the plunger 194, a lever 197 is adjustably fulcrumed at one extremity as at 198 on a bracket 199, see Fig. 3, which may as usual be secured to the platform or frame plate 5 the manner of fulcruming said lever preferably being as shown in detail in Figs. 5 and 6 and at its opposite extremity said lever is formed as a fork or yoke and pivotally connected to a pivot block 200, the latter being adjustably secured on the plunger stem 194 as by screws 200. Thelever 197 is pro vided with a cam roller 197 adapted to contact with a cam 201, see Fig. 3, the latter being adjustably mounted preferably as in Figs. 7 and 8 onthe shaft 150, the spring 195 serving to maintain the cam roller 197 in contact with cam 201 and apply regulablc pressure and variable travel to the piston 194, and as the fulcrum point 198 of lever 19"- may be shifted while in operation and the angular position of cam 201 also varied while in operation, the reciprocation and phase of re ciprocation of said plunger 194 may be likewise varied, to'thereby measure the charges of material and time of application of the same while the device is operating to deliver said charges. To provide for automatic equalization of the charges as in the pug-mill assembly, the lever 197 is formed with a toothed portion 202, an adjustable length contact pin 203 being adjustably secured as by screw 203, see Fig. 3, on a supporting shaft or bar 204, the latter being rotatably mounted in a journal bracket 204 which is suitably secured to the one extremity of bracket 187, and at a point adjacent to or above the lever 166 an arm 205 is adj ustably secured thereon as by screw 205, an adjustable-length connecting rod 206 being pivoted at one extremity on said arm and at its opposite extremity pivotally connected to the lever 166, see Fig. 1. In operation, the contact collar or nut 182 of stem 181 may be given a predetermined adjustment to contact with lever 166 at each stroke of piston 180, thus rotating shaft 204 and swinging the point or edge of contact pin 203 varying distances to engage the toothed portion 202 of lever 197 at varying points, depending upon the lowermost point reached by contact collar or nut 182 and which is governed by the size of the charge. Thus if a charge is abnormally heavy, the piston will only descend to a certain point and nut or collar 182 will give a correspondingly limited abtuation to lever 166 and arcuato swinging movement to pin 203, which will accordingly limit the succeeding stroke of lever 197. To return the lever 166 to its normal working position preparatory to a succeeding stroke, the lever bearing the contact pin 183 may remain connected up to operate as in the pugmill assembly.

Figs. 11 and 12 illustrate a valve structure and actuating means therefor adapted for controlling the application of a fluid medium, including super and/or sub-atmosphere to such parts of the apparatus as may be desirable. The valve herein shown comprises a casing 207, which may be adjustably supported from a part of the frame of the apparatus as by inserting suitable fastening devices in enlarged openings 208 or by a thread bolt 209, threaded at one extremity into said casing and at its opposite extremity extending through an enlarged opening and adjustably secured as by nuts 210, a chamber 211 being provided in the casing, a plunger 212 being mounted to reciprocate in said chamber and provided with ports 213 and 214:, said casing also having formed therein ports 215, 216 and 217, which are enlarged and interiorly threaded to receive nipples for connection of suitable flexible members or hose 218,219 and 220. The plunger is formed as a bracket at one extremity, as at 221, slotted or cast with an open portion as at 222,

to enable application over an actuating shaft which in this instance may be the shaft 150 or the shaft 55, the shaft in Figs. 11 and 12 being indicated as 150, cam-contact members or pins 223 and 22 1 being secured in or cast integral with said bracket and projecting at right angles therefrom, said pins being adapted to contact with cams 225, 226, 227 and 228 which serve to control complete and intermediate shifting of the plunger in both directions, said cams being preferably adjustably mounted as in Figs. 9 and 10. Or-

. dinarily frictional contact will serve to maintain the plunger 212 in shifted position, but to balance the weight of said plunger and ensure its remaining in shifted position, the one extremity thereof is notched as at 229 and the casing bored and threaded to house a resiliently mounted registering assembly or detent structure shown in the form of a ball 230, spring 231 and screw 232, the notches 229 being spaced in accordance with the shifting movement of plunger 212. Thus.

when the plunger reaches its approximate shifted position, the ball 230 will engage in one of the notches 229and releasably hold the plunger in shifted position. As each cam is so mounted as to permit adjustment thereof while in operation, the plunger may be timed and given varying dwell periodsand degrees of shift while the valve is functioning, to thus time and regulate the dwell of application of the fluid medium. Any number of these Valves may be provided, the flexible members or hose 218 and 220'leading to a source of I .supply of super andsub-atmosphere or other medium, .or one of said members may lead simply to the atmosphere, and the flexible plug 12 member or hose 219 leading to the point of application or introduction of the medium.

The spindles 11 are provided with longisee Fig. 14, and bored to provide a passageregistering with passageway 12 and way 12 opening out in the top of the chuck at the central and other ortions of the latter, the central opening being closed by a screw plug 12 and the chuck being formed with a further bore or passageway 12 leading to the atmosphere, for a purpose which will be hereinafter apparent. Vhile the usual type of plaster mold may be used to advantage in the present apparatus, it is preferred to use the form of mold shown in section in Fig. 14: and comprising a body or clay-receiving portion a of porous material such as plaster, and a metal base 6 the body and base portions being detachably associated as by a ring 0, chambers e and f. being formed in the mold, and when the mold is seated on the chuck these chambers are sealed, the chucks preferably being provided with suitable sealing means such as a flexible peripheral valve 12' and embedded rings 12" which also serve as cushioning means.

It will be seen that when the mold is seated on the chuck, a sub or super-atmospheric condition may be created in the chambers e and f and which is communicated to the surface of the mold and the clay or ware that may be disposed thereon through the porous body a of the mold, or selectively as by providing vents g in the mold or body portion a thereof. The passageway or bore 12 provides independent control of the chamber 6, and the may be used to selectively close the passageways leading to the chambers e and f, it being obvious that any number of these plugs may be provided.

It may be desirable in some instances to apply air under pressure to the under portion of the molds to such an extent as will require additional means other than the force of gravity or weight of the molds and Ware to maintain the molds in stable position on the chucks, in which event the chuck may be provided with a coil as at 232 and the spindles 11 with. commutators adapted to make intermittent contact with brushes which may be supported from .the frame units 9. A suitable switch generally indicated at S in Fig. 11 may be associated with the plunger bracket 221, andthrough the medium of which the chuck may be magnetized and de-magnetized during reciprocation of the chuck, to attract and repel the mold relatively to the chuck. For a more complete description of this magnet and switch structure, reference is made to my coto which they may be adapted, as for applypending application Serial No. 275,395, filed ing a lubricant, coloring uid, powder, eta, May 5, 1928. s and these members may also be ad usted so The shafts 64, 7 9 and 150 are preferably as to protrude from or recede into thefacing t provided with sprockets or analogous mem- 93 and form indentations or protruslons or '0 hers and connected by a suitable positive designs in or on the ware.

In this instance the vWare, then the mold should be formed with cooperating designs orindentations as at 236, the clay being originally smoothed or pressed thereinto by the profile. The vents in the mold may be formed at such points as it is desired to concentrate the force of the air under pressure or super-atmosphere, and likewise the facing 93 may be formed with vents to concentrate the application of subatmosphere, or vice versa. When the head 92 contacts with the mold having the freshly jiggered ware thereon, air under pressure may be applied to the mold, to conformthe soft ware to the shape of the working surface of the facing 93 and, if necessary, subatmosphere pressure may be applied to the facing 93 to assist in this operation. It'will be noted that the ware is practically enclosed on all sides by the facing and mold. The plugs 12 may be utilized, by providing any number thereof and interchanging their positions, to, concentrate the super and/or subatmosphere in either of the chambers e or f of the mold, and if the force of the air under pressure should have a tendency to displace the mold on the chuck, the switch S may be rendered operative to magnetize the chuck and attract the metal base I) of the mold. In this instance the chamber or orifice 105 may be dispensed with, the component parts of the head 92 being indicated by like reference numerals but slightly modified to ada t the head to the foregoing operations. 5 glutinants may be added to the clay mixture to condition the latter when producing ware by the foregoing method.

In some instances it may be desired to decorate or otherwise treat the ware as by print ing, stamping, sponging, ground laying, dustmg, etc., before firing, and in Fig. 15 an attachment particularly adapted for this purpose is illustrated. The facing 93 may be comprised of suitable material in accordance with the work involved, as for instance rubber, felt, sponge, etc., and supplied with the required coloring fluid, oil and the like through the medium of the member diagrammatically illustrated at 237, which may be in the form of a stamp pad, platen and the like and adjustably supported from a bracket 238. In the instance shown the pad member 237 is provided with a plurality of chambers 239 .and hose-attaching nipples 240 communicating with said chambers, to illustrate how, in stamping for instance, a suitable coloring fluid or fluids may be supplied to the.

chambers 239 and exude to the surface of the ad. A nozzle member 241 having a plurallty of supply branches is also illustrated, to indicate how the facing 93 may be sprayed or otherwise treated by application of a fluid or combination-of fluids or other mediums. In operation, the head 92 may be actuated to alternately move the facing 93 against the pad or other member237 and the ware, and during the arcuate movement of the head past the nozzle 241, a suitable spray of fluid, dust or the like may be applied to the facing before or after being pressed against the pad 237, the dotted position showing the head 92 against the pad, or in some instances only the nozzle may be necessary to apply the fluid or other medium to the facing 93 While in others only the member 237 may be required. The member 237 may be formed with designs of absorbent material in relief, as a ring or star, the design, name or other marking being applied to the facing and then to the ware. Any desired medium may be applied to the facing 93 through the ports 107 and'108 or orifice 105 in cooperation with the members 241 and 237.

Incrustations may be applied to the ware by sinking or otherwise forming a design in the members 99, filling the design with clay or other material by moving the facing 93 hearing said membersagainst the pad 237,

holding the clay or other material in the design, if necessary, by sub-atmosphere, then moving the facing against the ware to apply the design .or incrustation, and finally releasing the clay or other material by super-atmosphere or air under pressure. The material may also be applied to the members 99 through the nozzle 241 or treated during movement past said nozzle.

In Fig. 16 the attachment is particularly adapted for decorating the interior of deep ware, a plurality of resiliently mounted decorating or stamping members or tools 237 being provided. In this instance the assembly' comprises a main support. or cross-head 242, slotted as at 242*, brackets 243 also slotted at 243*, cylinders 244, pistons 245, springs 246 and nuts or bushings 246, the members or tools 237 being secured on the stems of the pistons 245. The cross head 242 is threaded on the holder 100 and the brackets 243 adjustably secured to the cross headby securing bolts passed through the slots 242 and 243,

the cylinders 244 being adjustably secured to 5 ible members 249 communicating with the duct 108, which in, is formed in the holder ing the interior of deep or un 'll'he members-23'? are chambered as at 249, said chambers communicating with the working surfaces of said members through ducts 2 19' and also having hose or analogous flexconnected thereto and this instance, also,

100 and cross head 242.

In operation, the decorating fluid or other material may be supplied to the members or tools 237 through the port or duct 108, and in order that the said members may be moved into and out of contact with the surface of the wars at substantially right angles relatively thereto, the valve shown in Figs. 11 and 12 may be connected up with the port or duct 107 and timed so as to admit air under pressure to the cylinders 244 through ports 248 when it is desired to retract the members 237 from the surface of the ware. springs 246 apply pressure to the members or tools 23'3"- and this pressure is adjustable through the medium of the threaded nuts or bushings 246*. To adjustably limit the maximum degree of extension of the members 237 the cylinder head is adjustably secured or threaded into the cylinder 244. Angular movement of the members 237* is prevented by pins 245*.

With this attachment the interior of deep ware may be decorated in various ways, as by applying colored patterns or designs in spaced relation around the interior side walls of the ware by reciprocating said members during rotation of the cross head 242, or said members may simply be moved into contact with the surface of the ware and the head 242 rotated, to coat the whole interior surface or form an annular ring or some similar design. I

Fig. 17 shows how an engraving or turning tool attachment may be applied to the appadriven in the instance shown, the otor 251 being adjustably secured to an attaching head which may be threaded or otherwise secured on the holder 100. The motor may be supplied with current through the medium of annular commutators 253, mounted on said head 252, and brushes 254, which are mounted on a non-rotating bracket posed between the gear 103 on the holder 100.

arious designs may be engraved in the ware, which may be in a soft, leather-hard or completely dried state, the head 252 being adapted to be rotated, reciprocated and tilted angularly, providing a means for guiding the tool as desired. Any form of tool may be used, as for instance an abrasive tool for smoothingpdried ware or cutting ofl projections or stubs and which is usually done by in nual labor.

A former or shaper 93*, preferably of-porous material, is provided and formedwith a threaded socket 257 for application to the holder 100, said former in the instance shown terminating in an exteriorly-threaded flared insulat0r-shaping head 258. The orifice or central passage 105 in this form of attachment may have a removable plug 259 applied to its lower extremity during certain shaping operations, as in making insulators, and super and sub-atmosphere as well as other fluid mediums may be applied through the orifice or passage 105 as well as through the ducts or passages 107 and 108.

illustrated and In making insulators the clay may be simply fed or dropped into the molds in suitable sized batches, and when the molds are advanced adjacent or under the apparatus, the shaper may be lowered into the mold and rotated at an angle and eccentrically relatively to the Vertical axis of the mold, the latter being rotated in the same direction, the clay being pressed against the sides of the mold as in the ordinary jiggering operation, or the clay may be preshaped or jiggered prior to being operated on' by the shaper. After the insulator has been formed or shaped, the

shaper 93 may be moved toward the center of the insulator sulficiently to clear the threads and/orundercut portion and the mold lowcred or the shaper elevated to'clear the insulator. Should the clay have a' tendency to adhere to the shaper, a suitable fluid medium may be applied through the passages 107 or 108 or orifice or well through the porous and providing a film clay which prevents shaper, The mold material of the shaper between the shaper and eing applied therearound.
